Specification of Letters Patent.

' Patented Jan. 25, 1916.

Application filed December 17, 191 1. SerialNo. 877,767.

T 0 all whom it may concern:

' Be it known that we, WILLIAM AMBnosn SALT and THOMAS SIMON BENNETT, residing at Providence, in the county of Providence and State of Rhode Island, have jointly invented a new and useful Improvement in Self-Adjusting Finger-Rings, of which the following is a specification.

In the construction of the usual rigid form of finger rings, the manufacturer is obliged to make fifty or more different sizes of each pattern or design, also where the wearer has proportionally large knuckles or finger joints a rigid ring, which would be a tight fit for the knuckle wouldbe loose on the finger, after passing the knuckle. This is objectionable in any finger ring and is extremely so in finger rings having a head or enlarged portion, which being coinparatively heavy causes the loose ring to slide around on the finger and thehead or ornamental portion to assume positions other than the correct position, which is on the back of the finger. I

The object of our invention is to improve the construction of a finger ring, whereby the above objectionable features are wholly eliminated.

Further objects of our invention are to construct a one piece jointless, solderless, self adjusting, expansible and contractible finger ring at a minimum of cost.

Our invention consists in the peculiar and novel construction of a one piece jointless,

solderless. self adjustin expansible and contractible finger ring. said finger ring having details of construction, as will be more fully set forth hereinafter and claimed.

Figure 1, is a side view of our improved finger ring, showing the same in its normal contracted position in full lines and in an expanded position in dotted lines. Fig. 2, is an edge view of the ring. Fig. 3, is a transverse sectional view throu h the ring taken on line 3. 3, of Fig. 1. Fig. 4, is an enlarged underside view of the blank from which the ring is formed. Fig. 5. is a longitudinal sectional view through the blank, taken on line 5, 5, of Fig. i. Fig. 6, is an enlarged sectional view through the ring,

taken on line 6, 6, of Fig. 2. Fig. 7. is an enlarged transverse sectional view through the ring, taken on line 7, 7, of Fig. 1. and Fig. 8, is an enlarged transverse detail sec tional view through the plate portion 0:;

the blank, taken on line 8, 8, of Fig. 4, showing the concavo-convex formation of the plate before the same is forced into place and flattened.

In the drawings, 9 indicates the head portion of our improved finger ring, said head portion 9 merging into a band portion 10 at one end and into a plate portion 11 at the opposite end. The head portion 9 has a shallow depression 19. in its underside, preferably the shape of the head portion 9, and forming practically a continuous raised edge 13 on the underside of the head portion 9. In the bottom of the depression 12 is formed a longitudinal groove 14, hav- 111g aproxlmately the wldth and thickness of the band portion 10 and at the intersection of the head and plate portions 9 and 11 is formed an aperture 15 the size and shape of the band portion 10. the free end of which. is formed into a hook shaped stop 16 which engages with a stop-shoulder 17 at the aperture end of the groove 14:. all formed integral. The plate portion 11 is first concavo-convex in cross section, it is first bent over and into the depression 12, and then flattened, thereby forcing the'edges of the plate against the raised ed e 13 of the head portion 9, firmly securing the plate in place flush with the inner surface of the ring. and forming a smooth surface on the inside of the ring. The free end of the band portion 10 is then sprung intorthe head portion 9 through the aperture 15, and lies in the groove 14.

The band 10 is normally in a contracted position as shown in full lines in Figs. 1 and 6. When in use the band 10 will expand when forced over a large finger-joint or knuckle, then contract as it passes by the knuckle and snugly fit the finger, there by giving a perfect fit and holding the head portion of the ring in the correct position on the back of the finger. The hook shaped stop 16 engages with the stop-shoulder 17 and limits the expansion movement of the band 10, thereby preventing the free end of the band from being drawn out of the head and distorting the rin Our improved fin er ring takes the place of a pluralitv of diiferent sizes of the old form of rigid fin er rings. it is formed in ne piece, it is solderless, jointless. self adusting, expansible and contractible. it may so of any size, shape or design, and may be,

manufactured at a minimum of cost or as expensive as desired;

We do not wishto confine ourselves to the exact construction shown as the same could be varied within the scope of the appended claims.

' Having thus described our invention we claim as new I p 1. A finger ring having a head having a depression in the base of the head, a groove in the bottom of the depression, a stopshoulder at one end of the groove and an aperture adjacent the stopshoulder, a contracted expansible band with a free end which-extends through the aperture and tits into the groox'e, a plate shaped to fit the depression and which fits into the depression Y and closes the same, and means on the free end of the band adapted to engage with the stop shoulder for limitlng the expanslon L movement or the band, all Iormed integral. 2. A fingerrmghavmg a head havlng a shallow depression in the base ofthe' head, a longitudinal groove in the bottom of the depression, a stop-shoulder at one end of i "the groove and an aperture adjacent the stcp shoulder, an expansible band with a .free end which extends through the aperture and fits intothe groove, a stop on the freeend of the band and a plate shaped to fit the depression and which fits into the depression and closes the same, all formed integral.

8. An ad ustable finger ring having a coinparatively large head, a shallow depression in the base of the head, a longitudinal the head extending into one end of the groove, a plate adapted to fill the depression and close the groove and a narrow band extending from the other end of the l head and having a free end adapted to extend through the aperture into the groove in the head, all formed integral.

In testimonv whereof, we have signed our names to this specification in the pres once of two subscribing witnesses.
